We look at the division of 86593040 by 80 
We want to divide 86593040 by 80.

Step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 80

Going ahead to step 2:
80 goes into 86 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 80 from 86 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 80

On to step 3:
80 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 65 and we're left with 65.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 80

Advancing to step 4:
80 can be fit into 659 8 times, resulting in a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtract 640 from 659 to get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 80

Step 5:
When dividing 193 by 80, we get 2 with a remainder of 33.
The next digit of our result is 2. 
Result so far: 1082.0
Subtracting 160 from 193 leaves us with 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 80

On to step 6:
When dividing 330 by 80, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 10824.0
Subtracting 320 from 330 leaves us with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 80

Going ahead to step 7:
104 divided by 80 is 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 108241.0
Subtracting 80 from 104 leaves us with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 80

On to step 8:
80 can be fit into 240 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 1082413.0
If we subtract 240 from 240, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1082413.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1082413.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 1082413.0 with a balance of 0.0.
